baseline period (1971-2000) mean of the global radiation observed at Jokioinen in southwestern Fin-
land (60.8◦N, 23.5◦E) for each calendar month. The thick black curve: the corresponding quantity
as an average of the simulations performed with 18 global climate models. Grey shaded area: mean

The hydrological simulations were performed with the Wa-
tershed Simulation and Forecasting System (WSFS) developed
and operated in the Finnish Environment Institute (Vehviläinen
et al., 2005). The WSFS is used in Finland for operational hydrolog-
ical forecasting and flood warnings (www.environment.fi/water-
forecast/), regulation planning and research purposes

than can be expected to originate from the cauldrons, three to four times the wa-
ter equivalent of the accumulation of snow over the watershed of the cauldrons. It has
been estimated that flow from the cauldrons, in addition to the jökulhlaups, could be
2–5 m3 s 1 at maximum (Vatnaskil, 2005). It is possible that part of the sulfate-rich
groundwater from the glacier comes from the cauldrons
